Jupyter notebook CSS styling pushes all content to the right side, and off screen, creating a large horizontal scroll bar. Content only displays on the right side of the page, when looking at any file or page in the browser. The issue occurs Firefox (79.0-1) and Google Chrome (84.0.4147.125-1). Happens on my desktop and laptop.

Inspected the page and found a CSS left-margin parameter that is roughly equal to half the page, appearing to be the cause. Attached a screenshot. Downgrading to jupyter-notebook-6.0.3-1 fixes the issue.

Affected version:
jupyter-notebook-6.1.1-1

OS: Arch Linux
Kernel: 5.8.12-arch1-1

Steps to reproduce:
Open terminal and launch jupyter notebook with jupyter notebook
